“…Afterwards, the phylogenetic tree was implemented with information gathered from papers focusing on phylogenetic relationships within brachyuran groups. In particular, the most useful papers were the ones by Lai et al [30][31][32][33][34]. In our analysis, we included almost all families (87 out of 96), with the exceptions being Aethridae, Acidopsidae, Atelecyclidae, Bythograeidae, Conleyidae, Crossotonotidae, Litocheiridae, Palicidae, Progeryonidae, because of lack of consensus about their phylogenetic relationships.…”

Improved heat tolerance in air drives the recurrent evolution of air-breathing

The transition to air-breathing by formerly aquatic species has occurred repeatedly and independently in fish, crabs and other animal phyla, but the proximate drivers of this key innovation remain a long-standing puzzle in evolutionary biology. Most studies attribute the onset of air-breathing to the repeated occurrence of aquatic hypoxia; however, this hypothesis leaves the current geographical distribution of the 300 genera of air-breathing crabs unexplained. Here, we show that their occurrence is mainly related to high environmental temperatures in the tropics. We also demonstrate in an amphibious crab that the reduced cost of oxygen supply in air extends aerobic performance to higher temperatures and thus widens the animal's thermal niche. These findings suggest that high water temperature as a driver consistently explains the numerous times air-breathing has evolved. The data also indicate a central role for oxygen-and capacity-limited thermal tolerance not only in shaping sensitivity to current climate change but also in underpinning the climate-dependent evolution of animals, in this case the evolution of air-breathing.

“…The validity of this genus, with respect to the subfamily Actaeinae, needs to be ascertained. But this is better done within the larger context of a systematic revision of the subfamily, which recent studies have shown to be polyphyletic, and with more attention given to the ventral or sternal characters and other nontraditional characters (see Lai et al, 2011). Furthermore, Odhnea (as Odhneria echinus) was shown to have a closer affinity to species traditionally classified under Xanthinae, such as Demania intermedia, rather than to actaeines (Lai et al, 2011: figure 1).…”

“…They are used in the transfer of spermatophores into the female seminal receptacles during mating (Bauer, 1986). They are of particular interest in the brachyuran male reproductive system, because they are morphologically diverse yet taxonomically very conservative, and hence provide valuable taxonomic and phylogenetic information (Beninger et al, 1991;Wee et al, 1995; * Corresponding author; e-mail: micaelavallina@conicet.gov.ar Goldstein and Dupré, 2010;Lai et al, 2010;Padate et al, 2010;Sal Moyano et al, 2011a;Guinot et al, 2013). The particular shapes of the gonopods and the presence of microstructures, suggest the hypothesis that they have different roles during copulation (mechanism of insertion, function of the setae) (Sal Moyano et al, 2011a).…”

A B S T R A C TOvalipes trimaculatus (de Haan, 1833) is a commercial species captured in the Mar del Plata coast, Argentina. However, no studies were conducted in order to study its population features neither its reproductive biology. The morphometric and physiological maturity of both sexes, the histology of the female seminal receptacle and ovary, and the ultrastructure of the male gonopods were studied in the present paper. In females, morphometric maturity (44.6 mm of carapace width, CW) was acquired prior to physiological maturity (54.6 mm CW). By contrast, in males, physiological maturity (46.6 mm CW) was acquired prior to morphometric maturity (52.3 mm CW). The ovary is connected to the dorsal part of the seminal receptacle. Neither Spermatophores, nor sperm packets were found inside the seminal receptacle; instead free spermatozoids were observed indicating that sperm from different males is probably mixed favoring sperm competition. The ultrastructure of the male gonopods was similar to the described for other Brachyura. Different types of setae and the presence of internal rosette glands were described and probable functions were suggested.
